SPECIFICATION forming part of Letters Patent N 0. 579,189, dated March23, 1897.

Application filed October 16,1896. Serial Noeoaors. on. model.)

To (tZZ whom it may concern:

Be it known that 1, CHARLES STADTFELD, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Corn-Planters and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to corn-planters, and is an improvement on thecorn-planter patented by myself September 29, 1896, numbered 568,722.

The details of the invention will be described in the followingspecification in connection with the accompanying drawings, of Which-Figure 1 is a plan view of a corn-planter having my improvementsthereon. Fig. 2 is a sectional elevation of the same. Fig. 3 is a sideelevation of one of the hiller or scraper bars with the ends broken off.Fig. 4 is an enlarged top view of one of the scraper-bars adjacent tothe hinge. Fig. 5 is a view 011 the line a; a: of Fig. 1. Fig. 6 is aView of the marker detached from the machine.

In the present invention the improvements appertain more particularly tothe construction of and the mechanism for actuating the scraper-bars,the position of the bars being practically the same as shown in myformer patent. These bars consist oftwo parts 1 and 2, which have ahinge connection by means of plates 3 and 4, which are rigidly attachedto said parts 1 and 2. The inner or overlapping ends of saidscraper-bars 1 and 2'are curved, as shown in Fig. 3, and fit one uponthe other.

5 designates a supporting bar or plate which is rigidly secured to thepart 2 of the scraperbar, incloses the connecting ends, and maintainssaid ends in close contact against any downward pressure that may beexerted against either part of said bar. The dotted lines in Fig. 3 showthe upward movement of the rear parts 2 of said scrapers when said partsare elevated in turning the machine around or at such other times thatit becomes necessary to raise the hoes 6 from the ground. The said hoesare suitably curved, have their ground ends pointed, and may beadjustably mounted on the rear end of the scraper-bars. The angle ofsaid hoes is substantially as shown in Fig. 2. As shown in Fig. 1, thescraper-bars are mounted parallel with the side bars 7 7 of thecarrying-frame and are inclosed adjacentto their connected ends bysupports 8, that are secured to the side bars of the frame. The rearparts 2 of the scraperbars are connected so as to move simultaneously bytransverse connecting-bars 9 9. The movement to elevate or lower theseparts of the scraper-bars can therefore be accomplished on one side ofthe machine by means of a curved bar 10, that is attached to one of theparts 2 andto an upright hand-lever 11, which has its fulcrum at 12.This lever 11 moves forward between two segment-gears 13, and it carriesa pawl 14, that engages with the teeth of said gears to hold the rearparts 2 of the scraper-bars in an elevated position. Each of the parts 1of said bars has a cam-bar 15 attached to it, against which a cam-wheel16 rides.

17 designates an antifriction-wheel mounted in line with the peripheryof each of the cams to lessen the friction when the actuating parts makecontact, which continues from a to b on the wheels. These Wheels 16 aremounted on a shaft 18 in the rear of the main axle 19 and are drivenfrom the latter axle by a sprocket-chain 20. It will be observed thatthe said shaft 18 will rotate continuously while the clutch mechanism 21is in gear. W'hen said clutch mechanism is out of gear, the shaft 18 maybe rotated by means of a ratchet- Wheel 22, which is rigid thereon.

23 is a lever loosely mounted on said shaft and inclosing the sides ofthe ratchet-wheel. This lever carries a pawl which engages with saidratchet-wheel to move it when the lever is moved forward. The use ofthese devices for actuating the shaft 18 is only intended for specialoccasions, for example, in covering a special hill of grain, one thathas been dropped near a stump or corner.

24 designates a marker which consists of two parts, one of whichprojects into a socket 25 in the front end of the frame, (see Fig. 1,)

so that portion Will occupy a horizontal position with the Wheel 26resting on the ground. The Weight of this Wheel Willfleave its impresson the ground to indicate the next row to follow.

Having fully described my invention, I claim- 1. In a corn-planter, thecombination with the carrying-frame, and the main axle, of hilling orscraper bars having their front ends rigidly attached to said frame, therear portions of said scraper-bars having a breakjoint connection, anddirt-scrapers or hoes attached thereto, cam-wheels mounted on a shaft inthe rear of the main axle and adapted to depress said scraper-bars atpredetermined times, and means for driving said shaft from the mainaxle, substantially as and for the purposes specified.

2. In a corn-planter, the combination With the carrying-frame, ofscraper-bars each consistin g of two hinged parts lying parallel withthe frame and having a rigid attachment to the front end of said frame,transverse bars connecting the rear ends of said scraperbars, a rotatingshaft mounted in the rear of and driven from the main axle, cam-Wheelsmounted on said shaft above the scraperbars, and cam-bars mounted onsaid scraperbars in line with said cam-Wheels, substantially as shownand described.

3. In a corn-planter, the combination With the carrying-frame, ofscraper-bars rigidly attached to the front portion of said frame, andeach consisting-of two parts 1 and 2, having their inner ends curved andoverlapping, a hinge connecting said two parts, transverse barsconnecting the rear parts 2, and hoes mounted thereon, a shaft mountedin the rear of and driven from the main axle, and cam- Wheels mounted onsaid shaft above the scraper -'bars and adapted to depress said bars,substantially as described.

4. In a corn-planter, the combination With the carrying-frame, ofscraper-bars consisting of two parts 1 and 2, the former rigidlyattached to the front end of the frame and both of said parts having ahinged connection inclosed by supporting-bars, a lever and connectionswith the parts 2 to elevate or lower said parts, a shaft mounted in therear of and driven from the main axle, ratchet devices to actuate saidshaft independently of the movement obtained from the main axle, andcams mounted on said shaft adapted to depress the scraper-barssubstantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.

CHARLES STADTFELD.
